Maybe they can call this The Giants Amendment. Or the Seubert Solution.

No matter what they call it, changes are coming to the NFL in the wake of the disastrous officiating gaffe that tainted the final seconds of last Sunday’s 39-38 Giants playoff loss to the 49ers.

The action is in direct response to the league’s rare admission that officials missed a pass interference call that should have resulted in the Giants getting a second crack at a potential game-winning field goal.

According to NFL commissioner Paul Tagliabue, the league will implement immediate changes in the mechanics of officiating, to go into effect for this weekend’s playoff games.

By now, fans of the Giants can recite in agonizing detail the sordid play-by-play of Sunday’s final six seconds. Matt Bryant lined up for a 41-yard field goal attempt, but the snap from Trey Junkin was low, forcing holder Matt Allen to reach forward to snare the ball, ruining the timing of the kick, which never came off. Allen scrambled to his feet, rolled to his right and tossed a wobbly pass in the direction of guard Rich Seubert, an eligible receiver who was in position to make the catch a few yards from the end zone before he was hauled down by 49ers defensive end Chike Okeafor.

Three flags were thrown on the play, all spotting guard Tam Hopkins for being an ineligible receiver downfield. If Okeafor had correctly been flagged for interference, the offsetting penalties would have resulted in one untimed play, allowing Bryant to again line up for a potential game-winning 41-yard field goal.

The league recognized two officiating breakdowns: Only the officials who threw the flags met with the referee in the chaotic scene. Second, officials were not in position to see the pass interference once the field goal attempt turned into a pass attempt.

The first change is that on calls in dispute at the end of games, the referee will check with all six officials to make sure no problem exists. The second change alters the position of two officials to provide better coverage downfield when a field goal attempt becomes a pass. The side judge, positioned behind the line of scrimmage, will stay where he is rather than sprint to the pylon. The head linesman, lined up at the end of the line of scrimmage, will release downfield to the corner to follow the action.

“In theory it sounds like a good idea,” John Mara, the Giants executive vice president and a member of the NFL’s Competition Committee, said yesterday. “At the very least we need to re-evaluate what we do at the end of the game and how the officials handle that situation. I had anticipated that would get done at the competition meetings in March, but apparently the commissioner wants to be a little more proactive than that and they want to get something done in time for this weekend.

“In a sense I kind of wish it would go away; on the other hand I think we have to take steps to make sure that it doesn’t happen again.”

Tagliabue said this is the most disappointing moment involving officiating in his 13 years as commissioner.

“It was a chaotic game, a chaotic second half,” Tagliabue told ESPN. “I think it was just the breakdown of communication within the crew in the sense that flags were thrown, with respect to one player being an ineligible receiver downfield, and as I understand at this point, most of the crew conference, if not all the crew conference, focused on those flags.”
